Abstract (en)
[origin: FR2797442A1] The invention concerns calixarene derivatives of formula (I), wherein: R<1> represents various hydrocarbon groups; R<2> and R<3> represent an alkyl, cycloalkyl, aryl group or a group of formula: O(CH2)n [O(CH2)p]q, OR<4>, or form together with the nitrogen atom a heterocyclic group; and m is equal to 6, 7, or 8. Said derivatives are useful for extracting strontium from aqueous solutions.
